摘要
选用当前在大田作物上常用的9种除草剂在糜子田进行不同剂量处理,对杂草的株防效、鲜质量防效、药害及产量进行调查分析,确定不同处理除草效果及对糜子产量的影响。结果表明,防治禾本科杂草效果较好的除草剂有480 g/L氟乐灵乳油1 125、2 250 m L/hm^2,33%二甲戊灵乳油2 250、4 500 m L/hm^2;综合防治阔叶杂草效果较好的除草剂有40%扑草净可湿性粉剂2 250 g/hm^2,短期对阔叶杂草防治效果较好的除草剂为42%丁·异·莠去津乳油3 000 m L/hm^2、40%异丙草·莠乳油6 000 m L/hm^2。
In this study,nine commonly used herbicides in field crops were used at different doses in Panicum milaceum L.fields to determine the efficacy of different herbicide treatments and their effect on millet yield.Weed control and fresh weight control effects,phytotoxicity and yield were determined.The herbicide with good effect for the control of grassy weeds were trifluralin 480 g/L EC(1 125、2 250 m L/hm^2),pendimethalin 33% EC(2 250,4 500 m L/hm^2).Prometryn 40% WP(2 250 m L/hm^2) provided a good comprehensive control of broad leaved weeds.Butachlor·isopropyl methyl·atrazine 42% EC(3 000 m L/hm^2) and isopropyl methyl·atrazine 40% EC(6 000 m L/hm^2) were effective for the short term control of broad leaved weeds.
